Description

Technical Field

[0001] The utility model relates to the technical field of plastic bags, in particular to a plastic bag with good heat preservation effect. Background Art

[0002] Plastic bags are bags made of plastic as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items. They are widely used because of their cheapness, extremely light weight, large capacity, and easy storage. However, due to the disadvantages of extremely long degradation cycle and difficult disposal of plastic bags, their production and use are banned in some countries. A plastic bag with good thermal insulation effect is a plastic bag with good thermal insulation effect.

[0003] The prior art patent document CN215591450U discloses a plastic bag. By adopting the above technical scheme, one kind of article is loaded into the bag body along the first opening, and different articles from the bag body are loaded into the sub-packaging bag along the second opening, so that the plastic bag as a whole is convenient for loading different kinds of articles, thereby reducing the use of extra plastic bags, and reducing the impact on the environment by reducing the use of plastic bags. The first handle makes it easy to lift the bag body, and the second handle makes it easy to lift the sub-packaging bag, so that it is convenient to load and transport articles. The sub-packaging bag is installed on the outer peripheral wall of the bag body, reducing the mutual contamination and influence between the articles in the bag body and the articles in the sub-packaging bag. When loading articles, the sub-packaging bag arranged on the peripheral wall of the bag body is convenient for loading a small number of small-volume articles. The second opening of the sub-packaging bag is in the same opening direction as the first opening of the bag body. When the second opening of the sub-packaging bag is in the same opening direction as the first opening of the bag body, it is convenient to simultaneously load the sub-packaging bag and the first opening of the bag body. The bag body is used to load items, and the second opening of the sub-packaging bag is opened in the opposite direction to the first opening of the bag body. When the types of items to be loaded are large and the quantity is small, the opening direction of the second opening is opposite to the opening direction of the first opening, thereby reducing the influence of the first opening on the loading of items at the second opening. The accommodating cavity makes it easy to load items and increases the types of loaded items. The sub-packaging bag is provided with mutually compatible snap buckles near the opening, and the sub-packaging bag is fastened by the snap buckles to reduce the leakage of items inside the sub-packaging bag and make the items more stable in the sub-packaging bag. The material of the bag body and the material of the sub-packaging bag are both plastic materials with strong wear resistance. When the bag body and the sub-packaging bag are loaded with items, the bag body and the sub-packaging bag have better performance due to their strong wear resistance. By adding sub-packaging bags to the bag body, the plastic bag as a whole is convenient for loading different types of items, thereby reducing the use of extra plastic bags, and reducing the impact on the environment by reducing the use of plastic bags.

[0004] However, due to the poor heat preservation effect of the plastic bag in the prior art CN215591450U patent, it is impossible to quickly and effectively insulate the plastic bag as needed during the actual use of the plastic bag, which is inconvenient to use the plastic bag and reduces the use experience of the plastic bag.
